8dc1db3172 drm/amdkfd: Introduce kfd_node struct (v5)
Introduce a new structure, kfd_node, which will now represent
a compute node. kfd_node is carved out of kfd_dev structure.
kfd_dev struct now will become the parent of kfd_node, and will
store common resources such as doorbells, GTT sub-alloctor etc.
kfd_node struct will store all resources specific to a compute
node, such as device queue manager, interrupt handling etc.

This is the first step in adding compute partition support in KFD.

v2: introduce kfd_node struct to gc v11 (Hawking)
v3: make reference to kfd_dev struct through kfd_node (Morris)
v4: use kfd_node instead for kfd isr/mqd functions (Morris)
v5: rebase (Alex)

664883ddde drm/amdkfd: fix dropped interrupt in kfd_int_process_v11
Shader wave interrupts were getting dropped in event_interrupt_wq_v11
if the PRIV bit was set to 1. This would often lead to a hang. Until
debugger logic is upstreamed, expand comment to stop early return.

3055e5d155 drm/amdkfd: Update event_interrupt_isr_v11 return
Add amdgpu_no_queue_eviction_on_vm_fault condition to
event_interrupt_isr_v11 return. If no queue eviction on vm fault
specified, function should return false for client/source ids specifying
vm fault.

594a1d0f34 drm/amdkfd: Return true/false (not 1/0) from bool functions
Return boolean values ("true" or "false") instead of 1 or 0 from bool
functions. This fixes the following warnings from coccicheck:

./drivers/gpu/drm/amd/amdkfd/kfd_int_process_v11.c:244:9-10: WARNING:
return of 0/1 in function 'event_interrupt_isr_v11' with return type
